Abstract
A lot of factors lead to the toxicity of nanomaterials such as:
1- Chemical composition.
2- Surface state.
3- Physical parameters.
4- Local chemical and physical environmental factors (Anna Gnach et al; 2015).
The chemical features of nanoparticles are important to be known, by detecting the methods and reactivity of nanoparticles when their surfaces interact with the living cells. This information is playing an important role in preventing the toxicity of engineered nanoparticles (Iversen T.G et al; 2011).
